<DIV></DIV>Hello all,<BR><BR>I am new to MPICH however i have read and google
ed about my question but couldn't find a solution. <BR>we have a cluster
consisting of a head node and 12 child nodes all running redhat AS V3.
<BR>head node <BR>runing pgi + mpich 1.2.6.2+wrf<BR>nfs share directory to all
child nodes where we keep programs we want to run with mpich<BR>we use rsh to
login since the system is on private newtork<BR>a node list with nodes name is
created and saved to the shared nfs direcotry<BR><BR>recently I reinstalled a
node with centos 5 and since we are not able to run mpirun on
it<BR><BR><I>/usr/local/mpich-1.2.6-2/bin/mpirun -p4pg nodes.list

file is nodes.list.</I><BR><BR>I have mounted the pgi directory on the child
node and still getting the error message. <BR><BR>Is the error related to the
fact that this child node is Centos5 where everything else is redhat? or the
version of redhat is old?<BR><BR>Thanks<BR></BLOCKQUOTE></BODY></HTML>
